Satunnaistus
Satunnaistus is the process of introducing randomness into the assignment of units, treatments, or outcomes, rather than deciding them deterministically. It is used to reduce bias, balance known and unknown confounding factors, and enable valid statistical inference.
In experimental design, random assignment of participants to treatment and control groups is standard practice. Common
Applications span clinical trials, social science experiments, and software development through A/B testing. In addition, randomization
Risks and limitations involve incomplete blinding, noncompliance, dropouts, or differential follow-up, which can introduce bias if
Historically, the emphasis on randomization grew with the development of modern experimental design in the early
